To all whom, it inlay concern:

13e it known that I, JASPER BLACKBURN, a citizen ol" the United States,and a resident of Chillicothe, Missouri, have invented certain new anduseful improvements in Anchors for tuy-Wires, of which the following isa specification containing a liull, clear, and exact description,reference being had to the accompanying drawings, 'forming a parthereol".

My invention relates to an anchor for guy wires; and the object et myinvention is to construct a simple inexpensive anchor lor guy-wires andthe like that is located in the ground and which will very firmly andthor oughly retain its position after once being located and which willrequire but very little manipulation while being placed in position.lll/ly invention consists in a baseplate which carries and on which isarranged to slidea pair of lates and means whereby said plates areshii'ted outwardly 'from the base plate when the device is anchored inthe ground.

My invention i'urther consists in certain novel features of constructionand arrangement ot' parts that will he hereinafter more lully shown,described, and claimed.

Figure 1 is a sectional view through the ground in which my improvedanchor is positioned and illustrating al wire supporting post with itsguy-wire attached to my improved anchor. Fig. 2 is a lplan view of myimproved anchor, the same ei g in a closed position in order to beinserted in the hole that is formed in the ground. Fig. 3 is a plan viewof the anchor after the same has been opened or moved into its anchoringposition at the bottom of the hole in which it is located. Fig. 4 is alongitudinal section taken on the line 4 4 oi Fig. 3. Fig. 5 is alongitudinal section taken on the line 5 5 of Fig. 3. Fi 6 illustratesthe anchor at the bottom of Vhe hole in which it is positioned andshowing the manner in which the sliding plates are spread apart. Fig. 7is a vertical section showing the preferred form of the device I makeuse of for spreading the plates of the anchor apart.

lteierring by numerals to the accompanying drawings, 1 indicates thebase-plate of my improved anchor, the same being preterably circular andof any size and material. Projecting upwardly from the center oi thisplate is a post 2, in the opposite sides off the uwer portion of whichis termed the horlzontally-arranged grooves 3. Formed through this postabove the grooves 3 is an aperture 4, in which is located the ends of alink 5, to which is fastened the lower end of the rod 6, that extendsabove the top of the ground and to which is secured the lower end o1 theguywire that is to be anchored.

Located on top of the plate 1 and adapted to slide thereon 1s a plate 7,which is preferably the same shape as is the plate 1, and formed in saidplate 7 is a slot 8, that receives the post 2 and permits said plate 7to slide upon the plate 1. The edges of the plate 7 adjacent this slot Stravel in the lower portion ofthe grooves 3. Formed in the under side ofthe plate 7 on opposite sides of the slot 8 and parallel therewith is apair of grooves 9, into which reject pins 10, that are formed integralwith the plate 1 and which pins Jform stops to limit the outwardmovement of the plate '7 These pins are so located and the slots 9 areof such a length as that the plate 7 is stopped in its outward limit ofmovement when the edge ci the plate is movedpso as to be in approximatealinement with the center of the post 2.

Formed integral with the top ol the plate 7 and in alinement with theslot 8 is a series oi u wardly-proje'cting lugs 11, by means of w richthe plate 7 is moved outwardlyupon the plate 1 through the medium oi aspreader hereinafter described. Located on top of the late 7 and adaptedto slide thereon is a simi ar plate 12, provided with a slot 13, thatperforms the same functions as does the slot 8, the edges of said plate12 adjacent the slot 13 traveling in the up )er portions of the grooves3. Formed in t e'under side of the late 12 is a pair of grooves 14, thatlie paralllel with the slot 13 and in which grooves are positioned theupper ends of pins 15, formed integral with the plate 1 and which pinsform stops to limit the outward movement of the plate 12. The edge ofthe plate 7 directly opposite these pins 15 is cut away, as indicated by16, in order that the plate 7 may be moved over onto the plate 1, sothat its edges coincide therewith. Formed integral with the top of theplate 12, in alinement with the slot 13 therein, is a series of lues 16,that are for the purpose ot receiving the end of the spreader that isutilized for moving the plates 7 and 12 outwardly.

The form ot' spreader that l prefer to use IOO and which is shown inFigs. 6 and 7 com rises a block 17, provided with a vertical s ot 18 andwhich is adapted to be removably positioned upon the upper end of thepost 2. Adapted to move outwardly and downwardly through the slot 18 isa bearing-block 19, that is connected by ball-and-socket joint 2() tothe lower end of a screw-rod 21, that passes through the u per end ofthe block 17. This bearing-b ook 19 carries a pair of outwardly anddownwardly projecting pawls 22, the lower ends of which are adapted toengage behind the lugs 11 and 16. The upper end of the screw-rod 21 issecured to the lower end of a suitable operating-handle 23.

To locate my improved anchor, a hole A is formed in the ground in directalinement with the guy-Wire that it is desired to anchor, and after saidhole is formed to the proper depth the anchor comprising the plates 1,7, and 12, which are arranged one on top of the other, as seen in Fig.2, are inserted in said hole and positioned at the lower end thereof.

The spreader, such as seen in Figs. 6 and 7, is now positioned upon theupper end of the post 2, and the lower ends of the pawls 22 are engagedbehind the pair of lugs 11 and 16 nearest the outer edges of the plates7 and 12. The handle 23 of said spreader is now manipulated so that thescrew-rod 21 is caused to travel through the upper end of the block 17,and as the bearing-block 19 moves downwardly the points of the pawls 22are moved outwardly, and as a result the plates 7 and 12 arecorrespondingly moved outwardly into the earth on opposite sides of thelower end of the hole.

If desired, the outer edges of the plates 7 and 12 may be sharpened orformed with knife-edges, although this is not absolutely necessary whensaid plates are comparatively t in.

When the plates 7 and 12 have been moved outwardly until the points ofthe paWls 22 disengage themselves from the lugs 11 and 16, the operationof the handle 23 is reversed to elevate the bearing-block 19, andconsequently withdraw the points of the pawls 22 until said pointsengage behind the next succeeding pair of lugs 11 and 16. The spreadingaction is then repeated until the plates 7 and 12 are moved to theiroutward limits of movement or until the pins 10 and 15 occupy the endsof the grooves 9 and 14. Thus the outer halves of the plates 7 and 12occupy positions in the undisturbed earth on opposite sides of a hole A,and thus a broad bearingsurface is formed at the lower end of the hole.The spreading device is now detached from the post 2, and the rod 6 isnow swung into position so that it lies in alinement with the post 2,after which earth is tamped into the hole A around said rod and on topof the plates at the bottom of said hole. Thus the anchor is verysecurely located, and the lower end of the guy-wire, such as B, issecured in any suitable manner to the loop formed on the upper end ofthe rod 6;

The plates 1, 7, and12 may be made in any size and of any thickness, andthey may be also made in various shapes, such as oblong or triangular,it only being necessary that the two upper plates be arranged to slideupon the lower plate and to be provided with means whereby theirmovement is limited, and they must necessarily be provided with lugs ornotches to receive the ends of a suitable spreading device.

A device of my improved construction provides a very effective anchor,inasmuch as the outer portions of the two upper plates eX- tend into theundisturbed earth on each side of the hole, and the entire surface ofthe three plates bearing against the earth creates great resistance toany pull upon the anchor when properly positioned.

The anchor is composed of a minimum number of parts, is easilymanipulated, and possesses superior advantages in point of simplicity,durability, and general efficiency.
